Abstract

OBJECTIVE: To determine which method of maggot debridement therapy- free-range or contained-is more effective for wound healing.

 

METHODS: In vivo study of 64 patients with 69 chronic wounds that showed signs of gangrenous or necrotic tissue. Patients were treated with either free-range or contained maggot debridement therapy according to maggot availability, dressing difficulty, and physician preference.

 

RESULTS: Significantly better outcomes were achieved with the free-range technique versus the contained technique (P = .028). With the free-range technique, the mean number of maggot applications and the total number of maggots per treatment were significantly lower than with the contained application technique (P = .028 and P < .001, respectively).

 

CONCLUSION: This clinical in vivo study supports in vitro studies in which containment of maggots was found to reduce the effectiveness of maggot debridement therapy.
